Specification of Letters Patent.

Application filed February 16, 1918. Serial No. 217,487.

To all whom it may o'ncem:

Be it known that I, WILLIAM B. ERSKINE, a citizen of the United States of America, and resident of Wheeling, county of Ohio, and State of West Virginia, have invented certain new and useful Improvements in Suspension Devices, of which the following is a specification.

This invention relates broadly to suspension devices, and more particularly to a lubricating device for the suspension hooks of porch swings, hammocks and the like.

The primary object of the invention is to provide a readily mountable and detachable coupling member or device, adapted for mounting between the upper end of a swing suspension chain and its supporting hook, which affords means for continually lubrifor eliminating the annoying squeaks and objectionable grating sounds commonly emitted by the engaging surfaces when chafing movement occurs between such surfaces.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which Figure 1 is a longitudinal section of the invention, applied;

ig. 2 is a central transverse sectlon of the same;

Fig. 3 is a view similar to Fig. 2 illustrating a hammock suspension device embodying the invention;

Fig. 4 is a side elevation, partially broken, illustrating a modification; and- Fig. 5 is an end elevation of the same.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views 1 indicates an oblong cup-like receptacle having located interiorly thereof midway between its ends an integral upwardly bowed member 2 which extends transversely from side to side thereof. Formed integral with said receptacle and depending centrally therefrom is a hook 3 adapted to receive thereon the upper end of a swing suspension chain.

The receptacle 1 is adapted for receiving therein in underlying supporting relation to the member 2 the lowermost part of a suspension hook 4 of that character commonly employed for supporting porch swings, the same being mounted in a ceiling or other overhead portion of a supporting structure.

The receptacle 1 is designed as a container for cup grease or other suitable lubricant whereby the engaging surfaces of the hookl and member 2 are continually lubricated, it being designed that said receptacle shall be filled with such lubricant to a level above that of the hook-engaged portion of said member.

l port designed to normally occupy an inclmed position, the receptacle 1 has its under inclined side wall of increased length so that the upper edge thereof will normally occupy approximately the horizontal plane of its shorter side wall, as shown.

In the modification illustrated in Figs. 4 and 5, a chain-supporting hook 3 and an eye member 5 for engagement with a suspension hook are formed of a single length of heavy wire, said eye member being formed by bending the wire intermediate its ends into loop shape and said hook 3* being formed by the ends of said wire disposed in parallel engaging relation. A receptacle 1 preferably pressed from sheet metal has the eye member 5 disposed therein and the hook 3 projected through its bottom. Vertically disposed grooves 6 pressed in the opposite side walls of said receptacle have opposite portions of said eye member seated therein so that the receptacle follows the swinging movements of the hook 3*.

at is claimed is As a new article of manufacture, a quickdetachable lubricator coupling for the openform supporting hooks of porch-swings, said coupling having a unitary structure and comprising a cup-like lubricant container, a

transverse supporting member located interioriy of said container and adapted to seat upon a supporting hook received Within said container, and a chain-supporting hook. depending from said container, said; container being of oblong form in horizontal section and having its bottom and end Walls curved to approximately correspond moles of this gated may be obtained for five cents each, "ray efiiressing the Commissiener oi Eatents, t1 eshington, D.

with the curvature of the open supporting hook to be received thereby;

In testimony whereof, 1 a'fiix my signature in presence of two subscribing Witnesses.
